strontium ferrite coercive

Research on La3+–Co2+-substituted strontium ferrite. Fig. 4, Fig. 5 show the effect of La 3+ –Co 2+ substitution on residual flux density (B r) and intrinsic coercive force (H cj) of sintered Sr ferrite magnets at different temperatures.It is well shown that La 3+ –Co 2+ substitution apparently increases intrinsic coercive force (H cj) from 301.2 kA/m at x=0 to the maximum value of 401.5

Ferrite magnets Properties

Different grades of ferrite magnets have different magnetic properties. You can find explanations about the parameters (remanence, Coercive Force, maximum energy and more) in our magnet glossary page. Ceramic magnets are available in both oriented (anisotropic) and non-oriented (isotropic) grades.

Estimate of the Anisotropy Field of Strontium Ferrite from

The isotropic Stoner-Wohlfarth model can be applied for the determination of the anisotropy field in powders. Samples of strontium ferrite - SrFe12O19 – were measured in Vibrating Sample Magnetometer (VSM). By means of the fitting of the first quadrant of the hysteresis curve the anisotropy field was estimated as 19-20 kOe for the SrFe12O19 phase.
